9 OPERATING MODES
9.1 Basic operating modes
The circuit can be powered up into different operating
modes, depending on the control bits RXON and SYNON,
via the 3-wire bus. This defines three main modes called
IDLE, SYN and RX mode.
The voltage level applied to pin RXCEN must be set HIGH
to enable the device. The VCO and the PLL sections are
enabled in SYN mode. In the RX mode every section is
enabled (receive part, VCO and PLL sections).
